Today there are countless new innovations that can be used to improve the lives of the world’s poor. Below are just 5 unique inventions that have the potential to vastly change lives.

The Hippo Roller – The Hippo roller gives people better access to water sources by allowing them to roll water containers across the ground. The trek to find water is a task that thousands of women and children must perform daily. They frequently walk long distances with heavy cans and containers to bring water home. The long walk is usually inefficient and arduous, and can often lead to spinal injuries as well. The Hippo Roller is an innovative device that allows people to roll 90 gallons of water across the ground. It consists of a barrel-shaped container that can be placed inside a rolling wheel. The container requires far less energy to move and can maximize the efficiency of carrying water.

The XO Laptop – The XO laptop is part of the One Laptop per Child campaign. It is a small computer specially designed for children in developing nations. The purpose of this computer is to give children across the world the opportunity to learn more, in addition to connecting them to the rest of the world. This durable, low cost machine is wireless and has a powerful screen that can be read in direct sunlight. The laptop is rugged enough for children who go to school outdoors and durable enough for children in the most remote regions. By giving each child an XO laptop, One Laptop Per Child hopes to promote self-empowered education.

The Peepoo Toilet – The Peepoo toilet is a slim biodegradable bag that can be used in the absence of a toilet or bathroom space. It is 10 grams in size and contains an inner layer that unfolds to form a wide tunnel. The bag has a urea liner that sanitizes the pathogens within human excrement. Within 2 to 4 weeks, the contents of the bag can be transformed into a fertilizer. Sound silly? In actuality, basic sanitation is something that 2.6 billion people in the world lack. Without proper latrines or hygienic facilities, humans can both contaminate the environment and transfer diseases to each other. The Peepoo toilet is just one way to protect environment and manage waste.

PlumpyNut – PlumpyNut is a ready to eat and ready made food that can be used to fight child malnutrition. It is basically comprised of peanut better, powdered milk, powdered sugar and vitamin and mineral enrichments. One serving of PlumpyNut contains the nutritional equivalent of one glass of milk and a multi-vitamin. It requires no water and no cooking to eat and a day’s supply costs only $1. The product supports rapid weight gain and its sweet taste has proved to be extremely appealing to young children. The organization Doctors Without Borders has seen the tremendous impact that PlumpyNut has on severely malnourished children in Niger, Africa. The nutritious peanut flavored paste has brought back countless children from the brink of starvation.

Jet Injection – Jet injectors use pressure to deliver vaccines and other immunizations directly into the skin. Rather than using needles, these medical devices provide vaccination through a fine stream of fluid that passes through skin into tissue. The model for the jet injector was actually used as early as the 1940s. Now they are disposable, and single use jet injectors help to eliminate the risk of re-using needles, particularly prevalent in low-resource regions. Regular needles run the risk of transferring diseases and can be easily misused. The Jet Injector allows for safer vaccination. Furthermore, jet injectors use 80 less vaccine than needle injections and therefore reduce waste and improve efficiency.
